As the core component of wall printer, the printhead precisely jets ink onto various surfaces to form high-resolution images, with Drop-on-Demand (DoD) piezoelectric technology dominating the industry due to its precision and reliability.
Leading models include multiple Epson series-specifically the DX7 (170/177 models), DX10 (TX800) and I3200-alongside industrial-grade alternatives like the Ricoh GH2220 (used by WallPen) and the Ricoh G6.
The selection of a printhead critically determines print quality, operational speed, maintenance efficiency, and durability, directly impacting project success and cost-effectiveness.
Key comparisons among mainstream Epson options (I3200, DX7, I1600, DX10) and Ricoh G6 further highlight performance variations, while the strategic choice between single or dual printhead configurations must align with specific application demands to optimize output and longevity. Here’s what we’ll introduce:

If you are new to the world of wall printing, you may want to learn about the printheads used and what they are used for. Modern wall printer primarily utilizes two types of printheads: Epson Micro Piezo and industrial-grade piezoelectric heads. Epson’s technology, particularly the Precision Core series, dominates the market due to its exceptional accuracy (up to 1440 dpi) and reliability.
These printheads employ microscopic piezoelectric elements that expand when electrically charged, propelling ink droplets with remarkable precision. You may be wondering: does all wall printer use the same printheads? What are the differences between them? Read on!
Wall Printer enables direct, high-precision printing onto vertical walls or floors, overcoming the substrate limitations of conventional printing methods. Utilizing industrial-grade piezoelectric printheads (e.g., Epson DX series), they achieve resolutions from 360 to 2880 dpi, accommodating irregular surfaces while producing sharp imagery and fine text detail.
The wall printer supports both water-based inks and UV-curing systems, enabling instant curing on dozens of construction materials including tile, glass, and metal. Integrated white ink channels ensure vibrant color reproduction on dark substrates.
Typical industrial models deliver production speeds of 7–12 sq. m/h, finding widespread application in architectural decoration, artistic murals, and industrial signage.
Typical wall printer printheads available on the market include Epson’s DX7, DX10, and i1600 models, among others.

The choice of printhead critically determines whether a wall printer delivers optimal performance or falls short. Standard printheads often fail to meet the demands of vertical printing applications. High-performance models-specifically those with high-pressure ink ejection (maintaining a nozzle-to-surface gap exceeding 10mm)-are essential. Industry-proven options include:
For cost-effective yet reliable solutions, wall printer manufacturers frequently adopt the DX7, DX10 (TX800), i1600, GH2220 (Ricoh’s compact model), G5, and G6, which strike an ideal balance between technical specifications and operational economics.
Through rigorous market analysis and comparative testing of wall printer printheads, we’ve evaluated critical parameters including ink compatibility, vertical printing range, and operational durability. This breakdown highlights the competitive advantages and limitations of leading models, empowering you to make data-driven decisions aligned with your project requirements-whether prioritizing precision, speed, or material versatility.
